A certain amount of diphenyl mixture of interior storage (accounts for about the one third of manifold volume to half), is heated by electrical bar,
Liquid phase is formed in cabinet, and system coexists.As long as the intracorporal pressure of guard box, it is ensured that the intracorporal temperature of case.Second is to make
It is concentrated and is heated with dinyl kettle, form circulating-heating circuit, this mode keeps the intracorporal temperature difference of case small, the production suitable for long filament.
The first heating method is due to using diphenyl mixture (biphenyl 26.5%, Biphenyl Ether in the manifold of coexistence of gas and liquid
It 76.5%) is heating carrier, the boiling point of this liquefied mixture under normal pressure is 258 degrees Celsius, so being 0.2Mpa in pressure
When can reach the temperature of manifold, the small no corrosion of internal pressure being subject in cabinet, manifold generally uses at present.
However, since temperature is high after the heating for diphenyl mixture, and pressure can also increase accordingly, therefore the safety of manifold
Property problem can not be ignored.
